Proportional representation. A major advantage of STV is that there is an easy to understand and manually count proportional version of it (called single transferable vote and used in Ireland). IMO it is best to go directly to multimember STV but single member RCV is at least a non-trivial improvement. I think the Irish system would be easier to switch to in the US vs other proportional systems. There won't be a huge change immediately, particularly when most of the country is still using a different system. It doesn't solve everything but it helps.
